Been there done that.
Corsa has no NPP valves.

Mine has been on the car well over a year and has yet to show any signs of rust. Daily driven!

I guess I just had bad luck, bought a 409SS muffler for my truck & in 6 months it had surface rust on about 50% of it. Drove it every day, now that I see how the 304SS stands up, I won't buy anything less.

I think that might be the best option actually, lots of sound level options and with LT Headers it might end up being about as loud as the Borla ATAK is right now.

Good think I kept the stock NPP mufflers.
